Adaptivity and adaptation

open access: yesProceedings of the International Conference on Networked Learning, 2008
Within the iClass (Integrated Project n° 507922) and Elektra (Strep n°027986) European projects, the authors were requested to harness their pedagogical knowledge to the production of educational adaptive systems. The paper pinpoints and documents difficulties and limitations of this work as well as the possible fertility of such kind of ...

Adaptive Demodulation in Differentially Coherent Phase Systems: Design and Performance Analysis

open access: yes, 2010
Adaptive Demodulation (ADM) is a newly proposed rate-adaptive system which operates without requiring Channel State Information (CSI) at the transmitter (unlike adaptive modulation) by using adaptive decision region boundaries at the receiver and ...

Comparison of Wavefront Sensing Methods for Solar Ground-Layer Adaptive Optics: Multi-Direction Averaging and Wide-Field Correlation

open access: yesPhotonics
Solar ground-layer adaptive optics (GLAO) is widely recognized as a key technology for achieving high-resolution, wide-field imaging in ground-based solar telescopes. However, the accuracy differences among various wavefront sensing methods in solar GLAO

Implementing Health‐Related Quality of Life Assessment in Pediatric Oncology: A Feasibility Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background There is growing interest in embedding health‐related quality of life (HRQoL) assessment and patient‐reported outcome measures (PROMs) within clinical cancer care. This study evaluated the feasibility, acceptability, and usability of implementing an electronic PROM (ePROM) platform to measure HRQoL in children with cancer ...

Fast Restoration of Aberration-Degraded Extended Object Based on Local Region Abstraction

open access: yesIEEE Photonics Journal, 2018
The compensating capability of wavefront sensorless adaptive optics (WFSless AO) system for extended object images degraded by aberration is severely limited to correction speed due to largely sized images and low frame rate of camera.
